The RP-Onesto 3-Pole Miniature Circuit Breaker (MCB) is a DIN rail-mount protective device rated C32A / 4.5kA at 415V, providing overload and short-circuit protection for three-phase low-voltage electrical installations in residential and light commercial distribution boards.

Key Features

• 3-pole design — protects all three phases simultaneously
• Rated current: 32A (C curve)
• Short-circuit breaking capacity: 4.5kA
• Rated voltage: 415V (three-phase)
• Mounts on standard 35mm DIN rail (EN 60715)
• IP20 protection — suitable for enclosed distribution boards
• Indoor use

Product Benefits

• C-curve tripping characteristic is designed for resistive and slightly inductive loads, covering most general three-phase circuits
• 4.5kA breaking capacity meets standard requirements for low-voltage residential and light commercial installations
• DIN rail mounting integrates directly into standard distribution boards without additional brackets
